That day may still be far off, but it’s clear that even with careers that take them all over the world, Pitt and Jolie, 35, have this whole being-a-family thing down to a science.

“On the road, we’re a military mobile unity,” Pitt said. "The kids have got their stuff down to one backpack, and they're each responsible for their own bag. Mom does the packing; she's quite gifted at that. Puts in just what we need – nothing extra."

They also do everything they can to make life as normal as possible for their boys and girls, he said. And that includes letting them know that they’re growing up in a loving home.

“We tell the kids, 'Mom and Dad are going off to kiss,” said Pitt. “They go, 'Eww, gross!'”
